Question

The metals obtained from their molten chlorides by the process of electrolytic reduction are ______.

Options

• Gold and silver

• Calcium and magnesium

• Aluminium and silver

• Sodium and iron

Answer 1

The metals obtained from their molten chlorides by the process of electrolytic reduction are calcium and magnesium.

Explanation:

The electrolytic reduction technique is used to extract highly reactive metals, such as calcium and magnesium, from their molten chlorides. Since these metals are too reactive to be reduced chemically, electrolysis is used to remove them.
